I am using the J51-GridGallery extension that comes with the paid template I bought. However, In the example, the image flips over horizontally, but when I make a new gallery from scratch, It doesn't work in the same way. Can you help me, please?

I thought I would explain myself better, I have made some screenshots to explain myself better.

The example of the J51-GridGallery I'm speaking of is on Beaufont template, when you hover over the picture,it flips to reveal the words, but on my current example the words are on the bottom, and on hover, the picture zooms.(which is not what I want) I download the template, it works when i copy the extension.

Can someone help me? I need it to work on another template.

Thanks
